Problems solved by technology

However, when the packaging requires white ink with high whiteness and fullness, it is not suitable to use UV white ink for printing iron
If the UV white ink of iron printing is used many times, it is easy to cause the paint explosion and poor adhesion in the white ink area of ​​the necking area.

Abstract

The invention provides a preparation method for anti-yellowing UV (ultraviolet) white tin printing ink, belongs to the field of UV tin printing ink, and can solve the problem of yellowing of general UV white tin printing ink under the irradiation of UV rays, especially in a subsequent polishing process. The preparation method mainly comprises the following steps: weighing the following raw materials in percentage by weight: 4%-7% of a polyester acrylate oligomer, 13%-16% of an acrylate prepolymer, 13%-15% of a polyester acrylate prepolymer, 4%-6% of a modified epoxy acrylate prepolymer, 0.3%-0.5% of a dispersant, 2%-3% of a rheological aid, 40%-45% of pigments, 3%-4% of fillers, 8%-11% of a photoinitiator and 1%-2% of monomers, wherein the photoinitiator comprises the following raw materials in percentage by weight: 2%-3% of 1-hydroxy-cyclohexyl benzophenone and 6%-8% of 2,4,6-trimethylbenzoyl-diphenyl phosphine oxide; stirring and standing for cooling; putting the photoinitiator into a cooled dispersion vat for stirring; rolling by a three-roller machine, putting the materials into a material vat for stirring, adding the monomers for adjusting the viscosity, packaging through the three-roller machine, and canning to obtain the anti-yellowing UV white tin printing ink.

Description

technical field [0001] The invention relates to the field of UV iron printing ink, in particular to a preparation method of anti-yellowing UV white ink for iron printing. Background technique [0002] In the iron printing and can making industry, the traditional printing iron curing is thermal curing, and most of them are cured by liquefied gas, coal and electric heating. From 2005 to now, my country's iron printing curing has undergone a transformation from traditional drying room drying to UV curing. [0003] UV ink is a specially formulated ink, and its composition generally mainly includes oligomers and / or prepolymers, pigments, monomers, photoinitiators, additives, etc. [0004] Among them, the oligomer or prepolymer provides the main performance of the ink film, which is an important component that determines the performance of the UV ink, and affects the hardness, friction resistance, adhesion, yellowing resistance, chemical resistance, water resistance, and processi...
